How do Juliet's parents react to her death?

Answer 1

The Nurse, having received no response to several calls, opens a curtain to see Juliet. She quickly determines Juliet to be dead and, shouting terrified laments, calls for Lady Capulet. She continues her mad grieving later when Capulet enters.

Paris first finds out through Capulet's rather fatalistic choice of wording and metaphor. Paris expresses sadness for the disappointment of his hopes of joy on this day in particular. He then joins the Nurse and Lady Capulet, violently expressing his despair. The three contrast with Capulet who, although not entirely composed, is more solemn and dark.
Paris blames Romeo for Juliet's death and forces him to fight when they meet in the graveyard. When Romeo strikes Paris down, Paris requests to be laid with Juliet's body. Romeo does not grant this request but feels pities Paris who died honorably.

Answer 2

Juliets family is heart broken. It makes her father realize that his war with Montague goes to far and he makes pace with him. Capulet also offers to raise a gold staute of Romeo after Montagye offers to raise a gold statue of Juliet.

Answer 3

He is very sad. He even goes to the tomb the day after the funeral to put flowers on it.

Answer 4

They are, not surprisingly, extremely upset at the death of their only daughter.
